Just two hours after a man robbed a bank Tuesday in Bethlehem's historic downtown, police headed to his home about six blocks away after receiving an anonymous tip identifying him from a surveillance photo.

Within minutes of the holdup just before 10 a.m. at the Wells Fargo bank on West Broad Street, police released crystal-clear photos showing a man who made no attempt to hide his face. They said he passed a teller a note saying "I have a gun" and fled with about $1,400.

By 12:15 p.m., police had received an anonymous call identifying the man as 32-year-old Aloysuis E. Mills, who lived in the 700 block of High Street. Authorities said that after the teller identified Mills from a photo lineup, police saw him leaving his home around 3 p.m., jumping into a red minivan.

Police followed with lights and sirens blaring, but Mills "took off at a high rate of speed" before he was stopped at Eighth Avenue and Schoenersville Road.

City police Chief Mark DiLuzio said the investigation was aided by tips in response to posts on both news and social media websites. He said Mills also is being investigated for possible involvement in other Bethlehem area robberies.

"The apprehension and arrest of this bank robber was the direct result of crime information being [given] to the public through both regular and social media, a public response and the quick actions of both Bethlehem police officers and state police troopers who were involved in the investigation," DiLuzio said.

At his hearing Tuesday evening before District Judge Roy Manwaring, Mills sat silently, wearing handcuffs, chains around his ankles and a white jumpsuit. Manwaring said the charges Mills faces "are very serious."

"You're in a pretty serious jam," he told Mills, who hung his head.

Mills told Manwaring he's lived at the High Street home in Bethlehem since December and previously lived in New York and South Carolina.

Police said Mills has a criminal record but weren't able to provide details. Manwaring said at the hearing that he reviewed Mills' prior criminal charges, calling them "not all that impressive."

"But clearly, you've raised the level of your game with these [new] charges," Manwaring said.

Mills was sent to Northampton County Prison under $100,000 bail on charges of robbery, terroristic threats, theft, receiving stolen property, reckless endangerment and fleeing police.

According to court records:

Just before 10 a.m., Mills came into the bank at 52 W. Broad St. He passed the teller the note about having a gun.

Mills said, "I have a gun, give me everything." The teller gave him $1,439 from the top drawer and Mills took off.

Surveillance photos show a man police identify as Mills, wearing a black-and-white striped shirt and gloves. After the robbery, he may have fled on a BMX-style bicycle.

Police credit the tipster with identifying Mills and leading them to his address. Mills' Pennsylvania driver's license photo matched the surveillance photo of the suspect, and investigators said the teller identified Mills through the photo lineup.

As officers surrounded Mills' home, they saw him leave in the minivan with a South Carolina license plate. Police tried to stop him, but he drove around the cruisers and sped off. They followed Mills as he drove northwest, turning onto Schoenersville Road.

At Eighth Avenue, police cut him off and arrested him. State police from the Bethlehem barracks helped in the capture.

Police said no one was hurt in either the robbery or Mills' capture. Mills' home was sealed off Tuesday afternoon as a crime scene, and DiLuzio said police were seeking a search warrant to look for evidence inside.

Most shop owners near the downtown Wells Fargo said Tuesday afternoon they had heard only a few details of the robbery. Some of the shops and restaurants in the area had not yet opened for the day when the holdup occurred.

As the city's streets filled late Tuesday afternoon with people coming to Musikfest, the 10-day festival that draws close to 1 million visitors, word of Mills' arrest had started to trickle out.

William Robertson of Easton said he's been attending Musikfest for years and has always felt safe because of a steady police presence.

"I'm glad to hear they caught [the suspect] so fast," Robertson said. "When you saw those photos, I figured they'd know who he was right away."
